Toughees shool shoes torn after being bought 2 weeks ago at Jet Store in Daveyton Mall

So I need clarity on the Toughees I bought 2 weeks ago that now all of the sudden it's opened on the sides, like my son had been wearing Toughees to school for years and this has never happened, or maybe it's because I bought them at Jet and it was the 1st time buying the Toughees since I was struggling with sizes at other shops. So please jet explain to me how's that possible, is it you or the manufacturer of Toughees that should be blamed for this inconvenience. Jet at Daveyton Mall like please explain to me what I should do next because I can't afford to buy another Toughees school shoes.
